The Magical ATM Card and SMS Message in Thailand

It was not too long ago that I penned Keyloggers: Why Banks Need Two-Factor Authentication. In that post, I briefly mentioned how a number of banks in Thailand use inexpensive SMS-based two-factor authentication (2FA) with one-time password (OTP) to authenticate transactions.

One of my favorite banks in Thailand is K-Bank. With K-Bank I can simply walk up to an ATM machine and pay a mobile phone bill, purchase mutual funds, buy insurance, or transact an ever-growing list of services payable at the modern and sleek K-Bank ATM.

For example, tomorrow I fly to Chiang Mai in Northern Thailand (Nok Air) and found K-Bank’s service amazingly better than in the US. For example, I booked my flight as usual (over the phone, but could have used the Internet) and told the reservation agent I was going to pay by ATM. He simply gave me a PayCode and told me I had three hours to go to the ATM and enter the PayCode to perfect my reservation.  I also got the PayCode via SMS.  This gave me the time I needed to make sure I had booked the perfect boutique hotel in Chiang Mai, the Fern Paradise.

Then, I went out into the beautiful Thai weather and completely my airline reservation at the ATM machine; which also printed out a receipt with my flight details and reservation number.

It sometimes amazes me how much further advanced some services are in Thailand compared to the US. To me, it feels more secure not to use an on-line payment center or give out my credit card details over the phone. I can simply book a ticket, take a PayCode, and complete the transaction at a nice modern, shiny, K-Bank ATM machine.

Who knows, maybe soon I can select the perfect window seat at the ATM and the receipt will act as my boarding pass!
